linear equations

[pedrodebem]

Hey, i was wondering if there was a way to solve linear equations with more variables than equations, so that the answer is a function of the extra variables.

I used to do something similar in matrixCalc:        

Thanks in advance.

This:

solve([(x1*(2*s+2)+x2*(s-1)) = (40+(20/s)),(30*s*x2-2*x1) = (25*s)],[x1,x2])

will return this:

{[(-25*s^2+1225*s+600)/(60*s^2+62*s-2),(25*s^3+25*s^2+40*s+20)/(30*s^3+31*s^2-s)]}

Thanks again road!
